I think the best way for you to go would be to visit your local recruiting office and ask to be put in touch with one of the PWRR Batallions. They will be able to give you up to date details of someone who will be able to answer your questions.
I could give you a lot of e-mail addresses for a number of PWRR personnel but I don't think they would be very happy with me.
I already have my Potentual Infatntry Officers FAM visit booked and AOSB briefing in may, my sponsor will be aranging me a vivsit to PWRR at Canterbury between the two I was just after some one who could give me more of a heads up for this. Prehaps my first post should have been a bit more detailed.
